Microsoft Team Shatters 40-Year Fiber Optic Bottleneck, Exceeding Traditional Glass in Speed and Loss
Lumenisity researchers, backed by Microsoft, have developed a hollow-core fiber optic cable with a record-low signal loss of 0.091 dB/km at 1550 nm, surpassing silica-based fibers. The Double Nested Anti-Resonant Non-Touch Fiber (DNANF) design utilizes concentric glass tubes to minimize signal degradation and interference. Tested on a 15km cable, the fiber exhibits low attenuation, broad bandwidth, and reduced dispersion. Microsoft plans to deploy 15,000 km within its Azure network, reducing amplifier needs and costs. This innovation promises faster data transmission, improved network reliability, and reduced energy consumption.
